Effect of Rhombohedral to Orthorhombic Transition on Magnetic and Dielectric Properties of La and Ti co-substituted BiFeO3
Pawan Kumar, Chandrakanta Panda, Manoranjan Kar
Polycrystalline La and Ti co-substituted ceramics were synthesized by the tartaric acid modified sol-gel technique. It was observed that the co-substitution of La & Ti at Bi & Fe s…
Effect of Structural Transition on Magnetic and Dielectric Properties of La and Mn co-substituted BiFeO3 Ceramics
Pawan Kumar, Manoranjan Kar
Bi1-xLaxFe1-xMnxO3 (x = 0.000 - 0.300) ceramics prepared by the tartaric acid modified sol-gel technique have been studied to analyze the effect of composition driven structural tr…
Carrier type modulation in current annealed graphene layers
Pawan Kumar, Amit Kumar
We report on the electrical properties of current annealed graphene and few layer graphene devices. It is observed that current annealing for several hours results the n-type dopin…
Effect of Structural Transition on Magnetic Properties of Ca and Mn co-substituted BiFeO3 Ceramics
Pawan Kumar, Manoranjan Kar
Composition-driven structural transitions in Bi1-xCaxFe1-xMnxO3 ceramics prepared by the tartaric acid modified sol-gel technique have been studied to analyze its effect on the mag…
